Just replace the water pump an had to remove drive belt an now it chirps at start up car has 70k on the should I replace the belt?

If it is a belt noise, sprinkling baby powder on the belt will make the noise go away. Apply liberaly with engine off onto the belt and start the vehicle. The belt may have gotten coolant on it and this will cause the chirp. Also a defective belt tensioner will cause the belt to chirp

my guess is your water pump is not working properly and the loud chirping sound is from the serpentine belt which also runs the water pump, alternator, ac and steering pump. first thing to check is coolant the cooling fan , thermostat , water pump in this order. chirping sound definitely come from the belt but the cause could come from any of the driven part but im zeroing in on the water pump because the car is running hot. old belt could also cause the chirping.

You must ensure that you place the correct measurement belt
Check belt tensioner
I think the water pump failure does not match the noise

Idler bearings are very common, they can also reduce the timing advance, reduce power in the engine

I want to say it is every 100,000 miles. At the same time you do the timing belt replace the water pump and belt tensioner as well. They may not seem bad but go ahead and do it while being in there. It will save you problems down the road

Replacing the belt is the least expensive thing you can do to fix a belt chirp. I think the belt is around $30-$40 if I recall and takes just 5-10 minutes to swap out. Otherwise, you're looking at a pulley problem, or waterpump starting to go out, or the belt tensioner and so on....

it could be water pump it could also be power steering pump or even the alternator but sounds like for sure one of the units that the belt drives

here you go. please rate, thanks

CAUTION: The drive belt tensioner has no provision for adjustment and will be damaged if forced to travel beyond its operating range. Automatic tensioners are calibrated at the factory to provide the correct amount of tension to the belt. There is no need to check tensioners for proper tension.
NOTE: Drive belts (8620) with automatic drive belt tensioner (6B209) do not require adjustment.
NOTE: When a drive belt is installed new or reinstalled after a service procedure, the drive belt does not fully seat into pulley grooves until engine has run for several minutes.
This vehicle is equipped with:

• a V-ribbed serpentine accessory drive belt.
• automatic drive belt tensioners.

New drive belts should be of the same type as originally installed.
Drive belt chirp is a regularly occurring chirping noise that occurs due to:

• pulley misalignment.
• excessive pulley runout.

It can be a result of a damaged pulley or an incorrectly replaced pulley that was not correctly aligned.
To correct drive belt chirp:

• determine the area where the noise comes from.
• check each of the pulleys in that area with a straightedge to the crankshaft pulley (6312) for front accessory drive and the water pump drive pulley to the water pump.
• look for the accessory pulley to be out of position in the fore/aft direction or at an angle to the straightedge.

Drive belt squeal is an intermittent noise that occurs when the drive belt slips on a pulley during certain conditions such as:

• engine start-up.
• rapid engine acceleration.
• A/C clutch engagement.

Drive belt squeal can occur under the following conditions:

• The A/C discharge pressure goes above specifications:
  • The A/C system is overcharged.
  • The A/C condenser airflow is blocked.

check belt for cracks or damage, also check tension on belt and tensioner, ensure no coolant got on belt. these all could cause chirp, as well as other accessory drives that work on same belt

Your 1997 Toyota with the 3.4 L V6 is an interference engine. This means if the belt breaks serious engine damage will occur. The belt must be replaced at 90,000 miles or 10 years under normal conditions and 60,000 under severe conditions. So, you need to have the belt replaced immediately as you are over the maximum of the belt's life. I would not drive this vehicle anywhere except to a trusted mechanic to have the belt replaced. The same belt that drives the cam also drives the water pump. In order to replace the water pump the cam belt must be removed. For that reason and the fact that the pump will not last 180,000 miles I highly recommend you have the water pump replaced at the same time as the cam belt. This will save you on labor cost later on when the pump would fail. Plus it might save more if the engine overheats. As you are going to replace the water pump this is a great time to drain and flush the cooling system and replace the thermostat which may or may not have been done in the past. You also will need to replace the spark plugs if that has never been done. Remember this is an INTERFERENCE engine. Keep driving the vehicle without replacing the belt and you are driving a time bomb that can explode at any time. Hope this is helpful to you.
